Photone - Grow Light Meter 3.5.3

Take the guesswork out of grow lighting! Our Photone grow light meter app is the ultimate solution for accurately measuring PAR / PPFD, lux, fc, and kelvin. This professional-grade app ensures precise measurements, making it a valuable tool for optimizing your plant's lighting needs.

When it comes to setting up optimal lighting for your plants, having a proper PAR / PPFD plant light meter is essential. Our app enables you to calculate the daily light integral (DLI) for your indoor garden, matching your plants' requirements and maximizing yield while minimizing electricity consumption.

Photone measures photosynthetically active radiation (PAR) as PPFD in µmol/m²/s, calculates the DLI in mol/m²/d, and measures illuminance in foot-candles or Lux. Additionally, it provides light temperature measurements in Kelvin, which helps determine if a light is suitable for fruiting and flowering or vegetative growth.

With its high level of accuracy, Photone stands out as the most reliable light meter app for plants. It achieves industrial-grade accuracy comparable to dedicated and expensive quantum PAR sensors. To learn more about our ±5% accuracy and how it compares to research-grade laboratory equipment, refer to our informative white paper: https://growlightmeter.com/whitepaper/

In addition to accurate measurements, the Photone app offers useful guiding articles to help you optimize your plant lighting. You can also find informative and educational content on our blog: https://growlightmeter.com/blog/
